In the framework of the design process of a multimodal 3D simulation environment to support architects' acoustic tasks, we wanted to gain a better understanding of how architects are able to discriminate the sounds using audio and/or visual inputs. T

An exact solution is developed for the sound field reflected by an infinite rigid rough surface with a periodic rectangular profile. The random-incidence scattering coefficient of this surface is derived from the numerical calculation of this solutio

A modification of the diffusion model’s boundary condition, based on the Eyring absorption coefficient, to account for high walls absorption is proposed. Numerical comparisons are carried out for three geometrical configurations (a proportionate ro

The coupling between a subsonic jet-slot oscillator (usually referred to as a slot-tone) and acoustical resonances of the flow supply duct is investigated experimentally. The aspect ratio of the jet height H to the slot stand-off distance L is varied

Industrial spaces are known to be very noisy working environment. This noise exposure can be uncomfortable, tiring, or even harmful, at worst. Industrial spaces have several characteristics: they are often huge flat volumes fitted with many obstacles

The ergodic propriety of a room has strong effects on its reverberation. If the room is ergodic, the reverberation can be broken up in two steps: a deterministic process followed by a stochastic one. The late reverberation can be then modeled by a re

In the context of the design of a multimodal environment for room acoustics evaluation, we investigate the link between a projected image and the sound of an acoustic simulation. 54 subjects have been tasked to judge the level of reverberation of a s

In this paper, a modification to the room-acoustic diffusion model is proposed to take different amounts of wall scattering into account. An extensive set of numerical simulations using a cone-tracing software has first been carried out, in order to

The acoustics of coupled rooms are characterized by energy exchanges through apertures and/or partition walls. The use of systems of diffusion equations allows to predict the temporal and spatial energy distributions in these configurations quite acc
